Waterproofing member for wire harness connecting portion

Abstract

A waterproofing member for a wire harness connecting portion of a motor for driving a window regulator of a vehicle is constructed such that it includes an opening being provided at each axial direction end portion of the waterproofing member, a mounting portion provided at one of the axial direction end portions of the waterproofing member, and fixed to the wire harness connecting portion so as to seal the wire harness connecting portion; a press-fit portion provided at the other of the axial direction end portions of the waterproofing member, and press-fit against a peripheral wall of the through-hole of the door panel so as to seal the through-hole; and further includes an elastic portion which is formed at an axial direction intermediate portion between the mounting portion and the press-fit portion and is formed so as to be elastically deformable along an axial direction of the waterproofing member, which elastic portion being able to change relative positions of the mounting portion and the press-fit portion by deforming elastically.

What is claimed is: 
     
       1. A waterproofing member for a wire harness connecting portion comprising: a closed tubular elastic portion with openings at both ends;   a mounting portion provided at one end of said elastic portion and fixed to the wire harness connecting portion;   a press-fit portion provided at the other end of said elastic portion and press-fitted against a through-hole of an inner door panel of a vehicle;   wherein said waterproofing member is located between the through-hole and a motor for driving a window regulator and   said press-fit portion has a fit-in-portion fit-in portion which is formed alone an axial direction of said waterproofing member and is fitted into the through-hole and a second flange portion which is formed alone a direction orthogonal to said axial direction and is press-fitted against a peripheral wall of-the through-hole.   
     
     
       2. A waterproofing member for a wire harness connecting portion according to claim 1, wherein said waterproofing member is substantially parallelepiped. 
     
     
       3. A waterproofing member for a wire harness connecting portion according to claim 1, wherein said elastic portion deforms in a substantially bellows-like manner. 
     
     
       4. A waterproofing member for a wire harness connecting portion according to claim 1, further comprising said wire harness connecting portion having a length, in a direction parallel to an output shaft of the motor, is less than a height of a housing in which the motor is accommodated. 
     
     
       5. A waterproofing member for a wire harness connecting portion according to claim 1, wherein said mounting portion has a first fit-in portion formed along the axial direction of said waterproofing member and is fit into a groove formed at the wire harness connecting portion of the motor, and a first flange portion formed along a direction orthogonal to said axial direction and is press-fit against a sealing seat surface formed at the wire harness connecting portion of the motor. 
     
     
       6. A waterproofing member for a wire harness connecting portion according to claim 5, wherein convex and concave portions are formed at a periphery of said first fit-in portion. 
     
     
       7. A waterproofing member for a wire harness connecting portion according to claim 5, wherein said first flange portion is formed integrally with said first fit-in portion and protrudes from an outer peripheral portion of said first fit-in portion. 
     
     
       8. A waterproofing member for a wire harness connecting portion according to claim 7, wherein said mounting portion is provided with a cover portion formed at a peripheral edge of said first flange portion and extending in an orthogonal direction to cover a peripheral edge portion of the wire harness connecting portion when the wire harness is fixed to the wire harness connecting portion. 
     
     
       9. A waterproofing member for a wire harness connecting portion according to claim 8, wherein said cover portion is formed at only three sides of the peripheral edge of said first flange portion. 
     
     
       10. A waterproofing member for a wire harness connecting portion according to claim 5, wherein said press-fit portion is formed continuously with said elastic portion and such that a diameter of said press-fit portion gradually increases. 
     
     
       11. A waterproofing member for a wire harness connecting portion according to claim 10, wherein said first flange portion projects in a step shape integrally from said first fit-in portion at an outer peripheral portion of said first fit-in portion. 
     
     
       12. A waterproofing member for a wire harness connecting portion according to claim 11, wherein a plurality of projections are formed at a periphery of said first fit-in portion along the axial direction of said waterproofing member. 
     
     
       13. A waterproofing member for a wire harness connecting portion comprising: a closed tubular elastic portion with openings at both ends;   a mounting portion comprising a press-fit portion and provided at one end of said elastic portion and being fixed to the wire harness connecting portion;   a press-fit portion having a circular shape, and provided at the other end of said elastic portion, and press-fitted against a peripheral wall of a through-hole of an inner door panel of a vehicle,   wherein said waterproofing member is located between the through-hole and a motor for driving a window regulator and at least one of said press-fit portion comprises a sealing seat.   
     
     
       14. A waterproofing member for a wire harness connecting portion comprising: a continuous closed tubular elastic tube with openings at both ends;   a first press-fit portion located at one end of said elastic tube fixed by said mounting portion to the wire harness connecting portion;   a second press-fit portion located at the other end of said elastic tube for press-fitting against a peripheral wall of a through-hole of an inner door panel of a vehicle,   wherein said waterproofing member is located between the through-hole and a motor for driving a window regulator and one of said press-fit portions having a sealing seat.
